Is spherical geometry non-Euclidean geometry?
Is spherical geometry non-Euclidean geometry? Each Non-Euclidean geometry is a consistent system of definitions, assumptions, and proofs that describe such objects as points, lines and planes. The two most common non-Euclidean geometries are spherical geometry and hyperbolic geometry. In spherical geometry there are no such lines. Where does Euclidean geometry not work?
